Gale climbed the lava slope, away round to the right of the arroyo, along an old trail that Yaqui said the Papagos had made before his own people had hunted there. Part way it led through spiked, crested, upheaved lava that would have been almost impassable even without its silver coating of choya cactus. There were benches and ledges and ridges bare and glistening in the sun. From the crests of these Yaqui's searching falcon gaze roved near and far for signs of sheep, and Gale used his glass on the reaches of lava that slanted steeply upward to the corrugated peaks, and down over endless heave and roll and red-waved slopes. The heat smoked up from the lava, and this, with the red color and the shiny choyas, gave the impression of a world of smoldering fire. Farther along the slope Yaqui halted and crawled behind projections to a point commanding a view over an extraordinary section of country. The peaks were off to the left. In the foreground were gullies, ridges, and canyons, arroyos, all glistening with choyas and some other and more numerous white bushes, and here and there towered a green cactus. This region was only a splintered and more devastated part of the volcanic slope, but it was miles in extent. Yaqui peeped over the top of a blunt block of lava and searched the sharp-billowed wilderness. Suddenly he grasped Gale and pointed across a deep wide gully. With the aid of his glass Gale saw five sheep. They were much larger than he had expected, dull brown in color, and two of them were rams with great curved horns. They were looking in his direction. Remembering what he had heard about the wonderful eyesight of these mountain animals, Gale could only conclude that they had seen the hunters. Then Yaqui's movements attracted and interested him. The Indian had brought with him a red scarf and a mesquite branch. He tied the scarf to the stick, and propped this up in a crack of the lava. The scarf waved in the wind. That done, the Indian bade Gale watch. Once again he leveled the glass at the sheep. All five were motionless, standing like statues, heads pointed across the gully. They were more than a mile distant. When Gale looked without his glass they merged into the roughness of the lava. He was intensely interested. Did the sheep see the red scarf? It seemed incredible, but nothing else could account for that statuesque alertness. The sheep held this rigid position for perhaps fifteen minutes. Then the leading ram started to approach. The others followed. He took a few steps, then halted. Always he held his head up, nose pointed. "By George, they're coming!" exclaimed Gale. "They see that flag. They're hunting us. They're curious. If this doesn't beat me!" Evidently the Indian understood, for he grunted.
